This is an impressively large wave for the central coastline of NSW. The largest wave measured near Sydney during the notorious June 2016 swell event that caused caused significant coastal erosion was 12.0 metres. However, that swell approached Sydney from the east, which caused waves to strike the coast directly. By contrast, today's swell was coming from the south, allowing the largest waves to bypass most beaches.

Another waverider buoy located closer to the coast, near Botany Bay, registered maximum wave heights up to 10.63 metres on Thursday afternoon.

Damaging surf is likely to continue along parts of the NSW coast into Friday morning, before easing gradually during Friday and the weekend.

It was an aptly named Sunday today, with temperatures reaching 28 degrees in the city, and hitting 30 degrees for western Sydney.
A very weak seabreeze and increasing cloud will keep the temperatures up overnight, with the eastern suburbs looking to only drop to 16-to-18 degrees overnight.
On Monday, it will be another warm one.
